Ventilation system for bathroom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bathroom ventilation systems fail to maintain effective air circulation and odor removal when the bathroom door is closed, as the air intake does not match the air exhaust, leading to inadequate ventilation and potential germ proliferation.
Innovation Solution
A bi-directional ventilation system comprising an external air traveling tube, an internal air traveling tube, and a bi-directional ventilation tube with an air exhausting part and an air intake part, along with an intake adjusting member and an air purifying filter, which allows simultaneous air intake and exhaust, ensuring swift air circulation and odor removal even in an airtight state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional air exhausting facility is used to draw moisture and odor out of the bathroom, then air exhaust function is provided, but air intake is insufficient when the bathroom door is closed, leading to inadequate ventilation
Solution Approach 1:
The ventilation system is segmented into separate air exhaust and air intake pathways. The air exhaust facility draws air through dedicated exhaust pathways (first, second, and third exhaust pathways) while the air intake operates through the bi-directional ventilation tube, allowing independent optimization of each function.
Solution Approach 2:
The bi-directional ventilation tube acts as an intermediary device that introduces external air into the bathroom through the ceiling panel. This mediator component bridges the gap between external air sources and the internal bathroom environment, enabling air intake without requiring the bathroom door to be open.
2Reliability
If the air exhausting fan operates at high capacity to remove odor quickly, then odor removal efficiency improves, but the system becomes ineffective when the bathroom door is closed due to lack of air intake
Solution Approach 1:
The bi-directional ventilation tube provides multi-functionality by serving both as an air intake pathway and as a structural component integrated into the ceiling panel. It enables the system to adapt to different operational conditions (open or closed door) while maintaining reliable ventilation performance.
Solution Approach 2:
The system transitions from relying solely on vertical exhaust pathways to incorporating a horizontal air intake dimension through the bi-directional ventilation tube. This dimensional addition allows air to enter the bathroom through the ceiling from external sources, creating a three-dimensional air circulation pattern that works effectively even when the door is closed.
3Object-affected harmful factors
If multiple exhaust pathways are provided to cover different areas (bathroom interior and toilet area), then comprehensive air exhaust is achieved, but system complexity increases
Solution Approach 1:
Multiple exhaust pathways (first, second, and third exhaust pathways) are merged into a unified ventilation system that shares common components including the air exhausting fan, the internal air traveling tube, and the bi-directional ventilation tube. This merging approach maintains comprehensive odor and moisture removal coverage while reducing overall system complexity through shared infrastructure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides efficient air circulation and odor removal, reducing the load on the air exhausting fan, minimizing germ proliferation, and maintaining a pleasant atmosphere by adjusting air intake and exhaust based on need, while preventing vortex formation and ensuring clean air circulation.
Implementation Method 1
an air intake fan 150 that takes air in from an outside and moves the taken-in air to an inside of the bathroom
Implementation Method 2
an air exhausting fan 250 that draws air from the inside of the bathroom to the outside
